E-mail: [email protected] A new species of Zeuxevania Kieffer, 1902 is described and illustrated from Yunnan, China: Zeuxevania orientalis Li & Xu, sp. nov.. A key to the species of Zeuxevania is provided. Zeuxevania Kieffer, 1902 is a small and rare genus of Evaniidae (Hymenoptera), with eight valid described species reported in Afrotropical and Palearctic regions (Deans 2005; Deans et al. 2016). The genus of Zeuxevania is characterized by the following characters: antenna 13-segmented; head often appearing globular in lateral view; fore wing with six closed cells, vein 1RS missing, fusing basal and 1st submarginal cells; both 1cu-a and 2cu-a present; distance between mid and hind coxae 0.6 × or less distance between fore and mid coxae; hind tibia and tarsus without prominent spines. Prior to this paper no species of Zeuxevania had been recorded from the Oriental region or China. Here one new species is discovered and described from China, Yunnan, representing the first record of the genus from the Oriental region. Material and methods Specimens were examined under a Motic SMZ-168 stereomicroscope. All photographs were taken with a digital camera Cool SNAP attached to the Zeiss Stemi 2000-cs stereomicroscope and processed by using Image-Pro Plus software. Figures were finished with Photoshop CC 2015.0.0, mostly to adjust the size and background. Terminology of wing venation follows Deans & Huben (2003), other morphological terms mainly follow the Hymenoptera Anatomy Ontology Portal (HAO Portal) (Yoder et al. 2010) and Kawada (2011). Measurements in descriptions are relative, except for body length and fore wing length reported in millimeters. Abbreviations used in the text are: POL= the shortest distance between posterior ocelli; OOL= the shortest distance between posterior ocellus and compound eye; OD=the diameter of ocellus. The holotype of new species is deposited in the Hymenoptera collection of South China Agricultural University, Guangzhou (SCAU). Genus Zeuxevania Kieffer, 1902 Zeuxevania Kieffer, 1902: 4.

Several cladograms using the complete species sample, but obtained with different weightings, are presented. Local studies were also carried out to provide possible alternate topologies. The deep nodes of the trees were unstable and were never supported, but most of the superficial nodes were stable and robust. The results therefore provide support for a generic classification of the subfamily. The large genus Eurytoma – which includes about half of the described species of the subfamily – proved to be polyphyletic, and is redefined in a nar- rowed sense using putative synapomorphies. Bruchophagus and Prodecatoma were similarly redefined. The genera Philolema and Aximopsis are reconsidered and defined in a broader concept. A number of the species presently included in Eurytoma were transferred to these genera. Finally, 22 new generic synonymies are proposed and 33 spe- cies are transferred. The study also demonstrates that the Eurytomidae are polyphyletic.

E-mail: [email protected] 2Department of Entomology, Royal Ontario Museum, Toronto, Ontario, Canada, M5S 2C6 and Department of Ecology and Evolutionary Biology, University of Toronto, Toronto, Ontario, Canada, M5S 1A. E-mail: [email protected] Abstract Palaeocharis rex n. gen. and sp. (Eucharitidae: Eucharitinae) and Perilampus pisticus n. sp. (Perilampidae: Perilampinae) are described from Baltic amber. Perilampus renzii (Peñalver & Engel) is transferred to Torymidae: Palaeotorymus renzii n. comb. Palaeocharis is related to Psilocharis Heraty based on presence of one anellus, linear mandibular depression, dorsal axillular groove, free prepectus and a transverse row of hairs on the hypopygium. This fossil is unique in comparison with extant Chalcidoidea because there are two foretibial spurs instead of a single well- developed calcar. Perilampus pisticus is placed into the extant Perilampus micans group because the frenum and marginal rim of the scutellum are visible in dorsal view and the prepectus forms a large equilateral triangle. The phylogenetic placement of both genera is discussed based on an analysis of both a combined morphological and molecular (28S and 18S) and morphology-only matrix. Morphological characters were used from an earlier study of Eucharitidae (Heraty 2002), with some characters revised to reflect variation in Perilampinae. Baltic amber is of Eocene age, which puts the age of divergence of these families at more than 40 mya.

JUSSILA Abstract: The fauna of Ichneumonidae (Hymenoptera) from Golestan National Park and Vicinity (Northeastern Iran) is studied in this paper. In a total of 14 species from 14 genera (Pristomerus, Temelucha, Aclastus, Gambus, Barytarbes, Diadromus, Rhexidermus, Megastylus, Phaestacoenitus, Endromopoda, Rhyssa, Scambus, Strongylopsis, Lathrolestes), and 8 subfamilies (Cremastinae, Cryptinae, Ctenopelmatinae, Ichneumoninae, Orthocentrinae, Phuridinae, Pimplinae, Ctenopelmatinae) were collected from this large natural ecosystem. Key words: Ichneumonidae, Parasitoid, Fauna, New record, Golestan National Park, Iran. Introduction Conservation of natural resources today is a respected and well-merited doctrine at both national and international levels. National parks possessing diverse examples of biotic communication and ecosystems, serving as scientific land use model and representing outstanding values of natural heritage, are one of the means of expressing this doctrine. The distinguishing characteristic of national parks is the non consumptive use of natural resources. They also have many scientific, cultural, educational and recreational inherent values. The Golestan National Park was the first area in Iran to be designated as a national park. It is located at 37,16° to 37,36° north latitude and 55,44° to 56,17° east longitude and has an area of about 91.000 hectares.

    Arthropod fauna of the UAE, 6: 225–274 (2017) Order Hymenoptera, family Chalcididae Gérard Delvare INTRODUCTION The Chalcididae belong to a medium-sized family of parasitoids with 96 genera and 1469 species in the World (Aguiar et al., 2013). Their size ranges from 1.5 to 15 mm and their body is hard with surface sculpture consisting of umbilic punctures. They are predominantly black, sometimes with yellow and/or red markings, rarely with metallic reflections. The sexual dimorphism is minimal except in Haltichellinae, where the flagellum of the male is thicker and the scape possibly modified (Plates 18–21). Recognition: The family belongs to the huge superfamily Chalcidoidea, which now includes 22 families (Heraty et al., 2013). In this group the mesosoma exhibits a special triangular sclerite – the prepectus – which separates the pronotum from the tegula (Plates 7, 8). This plate is also present in Chalcididae but is quite reduced here (Plates 5, 29). The family is mostly recognized by the enlarged metafemur, which is toothed or serrulate on the ventral margin, and the strongly curved metatibia (Plates 26, 48, 57, 94, 131). Some representatives of other chalcid families (Torymidae: Podagrionini and some Pteromalidae: Cleonyminae) also have an enlarged metafemur (Plate 9) but here the prepectus is expanded as usual and well visible as a triangular plate (Plate 8); in addition the relevant groups exhibit metallic reflections (Plate 7). Finally the sculpture of the propodeum is quite different: it is almost always areolate in the Chalcididae (Plate 3), but never exhibits such ornamentation in the non-chalcidid families (Plate 6) The Leucospidae, with the single genus Leucospis Fabricius, 1775, would also be mixed with the Chalcididae as they also share their character states.

  • Biosystematics of Chalcididae (Chalcidoidea: Hymenoptera)
    Proc. Indian Acad. Sci. (Anim. Sci.), Vo!. 96, No. 5, September 1987, pp. 543-550. © Printed in India. Biosystematics of Chalcididae (Chalcidoidea: Hymenoptera) TC NARENDRAN and S AMARESWARA RAO Department of Zoology. University of Calicut, Calicut 673 635. India Abstract. The Chalcididae represent a large group of parasitic Hymenoptera which para­ sitise pupal or larval stages of various insects including several pests. Their phylogeny is not so far clearly known. but a Eurytomid-Torymid line of accent could be postulated. There is a general resemblance in their adult behaviour such as emergence, courtship, mating, oviposition. feeding etc. Their hosts belong to Lepidoptera, Dipteru, Hymenoptera, Neuroptera. Coleoptera and Strepsiptera. Keywords, Chalcididuc: Biosystematics. 1. Introduction The Chalcididae (S. Str.) represents a large group of parasitic wasps (Hymenoptera: Chalcidoidea) which parasitise various insects, many of which are of economic importance. Their hosts include the blackheaded caterpillar of coconut, the cotton leaf-roller, the padyskipper, the diamond back moth of cabbage, the gypsy moth, the castor capsule borer as well as extremely large number of other pests. Unfortunately many species.of Chalcididae look very much alike while they differ widely in habits. Hence, precise identification of the species or infraspecific categories is highly important in any host-parasite studies involving these insects which are important, interesting and difficult (taxonomically) parasitic insects. The study of Chalcididae may be said to have begun well before 200 years ago when Linnaeus (1758) discovered and reported a few species. Since then several authors have contributed to the knowledge of this family and some of the important contributions are those by Fabricius (1775, 1787), Walker (1834, 1841, 1862), Westwood (1829), Dalla Torre (1898), Dalman (1820), Spinola (1811), Motschulsky (1863), Forster (1859), Fonscolornbe (1840), Cresson (1872), Klug (1834) and Kirby (1883).
